Review: Absolute game-changer for vendor markets! - We’ve been using the EF ECOFLOW Portable Power Station 3600Wh DELTA Pro to run our heat press at vendor markets, and this thing is an absolute beast. It handles the load with zero issues. No voltage drops, no struggling, just smooth and consistent power the entire time. The 3600W output is more than enough for our setup, and having five 120V AC outlets makes it super easy to plug in everything we need without juggling extension cords. It fires up fast, runs quiet, and gives us total peace of mind when we’re on-site and making products live. Battery life is impressive. We can run multiple presses without constantly stressing about recharge time, and the build quality feels solid and professional. It’s clearly designed for real work, not just camping or emergency backup. If you do markets, pop-ups, mobile businesses, or anything that needs serious, reliable power without a generator, this is 100% worth it. One of the best investments we’ve made for our business. 💪🔋
Review: Best Yet! - Excellent portable power solution for camping, emergencies, or on-site work. Battery management is solid, with decent recharging options and a responsive display. It’s a bit heavy, but that’s expected for the capacity. Overall, a dependable, versatile unit.

## Questions & Answers

**Q: Tell us about the ecoflow pro solar generator. how many panels do we need to charge the battery’s?**
A: the number of panels depends on the amps and voltage rating of the panels you buy. the PRO'S RATINGS ARE total amps 15, total volts 150, total watts 1600. this means you add volts, amps, and watts for the total of them. so if you wire in series your panels you add all the panel volts, make sure no panel is more than 15 amps and total watts of all panels do not surpass 1600watts.  this is for a series hookup. you only add together the amps if you wire in parallel and use the lowest voltage off the lowest pannel.

**Q: how long will this run a refrigerator?**
A: There are multiple times depending on use.  If the door is not opened, the run time is longer, if the door is opened frequently while on the Ecoflow, it will not last as long.  I would recommend that restricted door opening be practiced in the event of a power outage to achieve maximum runtime while on battery backup.

**Q: Can I charge my large power station using another power station? a smaller one that can recharge faster using solar. to basically be my charge source.**
A: Yes you can charge from smaller station or directly from battery bank using AC or DC, but the DC will be limited to ~192W (24Vx8A) by the Delta Pro. The AC charging will be limited to 1800W or the output limit of the smaller power station which ever is lower. The Delta Pro has a 1600W input for solar which I believe would be the most efficient. I have tested DC charging from 24V Batteries using DC input port.

**Q: Assuming full sun, how long does it take to use solar to recharge this unit with the included panels (not looking for a depends answer?)**
A: I have mine in full sun and it is showing only 285 watts of power being generated and it started at 32% and showing 9 hours to full charge.

### ⭐⭐⭐⭐⭐ Upgrading from a previous ECOFLOW unit, looking forward to the extra storage and output of this unit
*by G***E on November 27, 2025*

This is our second ECOFLOW product we've owned. Our first was a Delta 2. It served us well, but ultimately it was too small. That's where this one comes into play. We chose this unit because of it's storage capacity, power output, ease of attachment with accessories and ECOFLOW's reputation. We could have gone a different route, such as a different brand or simply building my own solution, but ultimately this was the better solution for us. ECOFLOW is the solution to go with if you need a solution that works out of the box. We'll be using this unit with our 1400 W of solar panels we've assembled plus the Alternator Charger we bought to work with the previous unit. ECOFLOW has a good reputation regarding quality. Our previous unit never had any issues and I don't anticipate this one having any issues. One word of note - It's heavy. It rolls on built-in wheels and has a built-in handle to help get it around.
